Runway overrun excursions…

Boeing Safety - A top issue

U.S. NTSB - Runway safety - top 10 since 1991

Flight Safety Foundation - A top issue

IATA - Recognized accident issue

ICAO GRSS in May 2011 - A top issue

Runway excursions are the first leading cause of aviation accidents and the third leading cause of transport airplane fatalities


Boeing Overrun characteristics…

Decision height

Friction limited or runway contamination

Tailwind

Long landing

High touchdown

speed

Unstable approach (too high, too fast)

Reverser level too low or reduced too soon

AB too low

Reversers late or not deployed

Speedbrakes late or not deployed

Runway excursions often are caused by more than

one factor

Stability Touch-down Deceleration


Decision height

Embraer Overrun Characteristics…

Overrun excursions often are caused by more than one factor!

Stability Touch-down Configuration

Touchdown

Friction limited or runway

contamination

Crosswind

Long landing

Unstable approach

Vref excedance

Others

Insufficient braking



39 Overruns

Training Aid video

• Stable approach • Runway friction • Runway available vs. required • Reported conditions vary • Approach speed additives • Proper, timely use of deceleration

devices

Technology

• Approach planning tools • Runway positional awareness and • Runway alerting • Stability guidance and alerting • Predicted runway stop location • Overrun alerting

For every landing:

• Landing distance calculation • Go-around point • Utilize appropriate callouts


Training Video

Procedures

Procedures…


Perform a landing distance calculation and assessment Plan a go-around point or a latest touchdown point Ensure required procedural callouts are made

Note: A thrust reverser callout and a landing distance calculation were added to the FCTM and the FCOM

Procedures


Inadequate Deceleration Delayed Thrust Reverser (TR) Usage… Prompt TR command is critical Ground Idle from Flight Idle Example from data

When TR commanded

TR deploy & engine spool up

When Max. Reverse achieved

TD + 2 5 sec. TD + 7 TD + 6 11 sec. TD + 17
